VISOR.

Application filed November 21, 1923. Serial No. 676,153.

This invention relates particularly to visors involving a constructioncomprising a frame and a sheet or sheets of pyralin, celluloid, oranalogous material mounted in said frame.

The pyralin, celluloid or the like may be employed in a thin sheet, orsheets, in lieu of glass, and may be transparent, or semitransparent.The sheet material may be given any desired color however. Such materialis peculiarly subject to the influence of weather conditions, beingaffected by changes in temperature and perhaps by other changes inatmospheric conditions. The sheets are liable to arp and to otherwisechange then dimensions under ordinary conditions of use.

The primary object of the present invention is, therefore, to so formand support a sheet as to obviate undesirable deformation of the sheetin use, while at the same time providing for such expansion orcontraction as may be necessary.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in which 1 represents a plan view of the improvedvisor; Fig. 2, an end elevational view of the vis r, the supportingmeans being shown brolrenly, ant the visor being shown associated withan automobile top (shown brolrenly) Fig. 3, a plan view of one of thesheets of pyralin or celluloid employed; Fig. 4, a fragmentary iewshowing a portion of one of the celluloid sheets and a portion of aframe member; Fig. 5, an enlarged broken ectional view taken asindicated at line 5 'n. 1; Fig. 6, an enlarged broken seconal view takenas indicated line 6 of l; and Fig. 7, an enlarged broken sec- 0 al viewtaken as indicated at line 7 of l. n the embodiment shown, the visorcomprises a frame ii, and sheets B, B of pyralin or celluloid, mountedin said frame.

In the preferred embodiment of theframe, which is illustrated, a pair oflower marginal binding members 1, a pair of upper marginal bindingnembers 2, pairs of end marginal binding members 3, and a pair ofcentral marginal binding members ft are provi tied for supporting thecelluloid sheets B, B.

The marginal frame members 1 and 2 may be referred to as longitudinalframe members. and the frame members 3 and the frame members e may bereferred to as transverse frame members. Theframe members pref- ,erablyare formed of strips of sheet metal which are stamped into across-section of approximately U-form, as illustrated, for example, inFigs. 6 and 7. At suitable intervals, the web portion of each U-shapedmemher is struck inwardly, thus providing internal embossments *1, asshown in Fig. 6. These embossments are arranged in pairs and areperforated and receive rivets 1" which connect the members. As shown inFig. 6, the lower flanges of the U-shaped members abut against eachother as indicated at 1, and curved flanges I extend outwardly from theouter flanges, the upper one serving as a rain-trough which extendslongitudinally of the visor.

The inner flanges are spaced apart slightly, as indicated at l*, thusproviding space for the reception of the marginal portion of thecelluloid sheet B.

Each member 3 comprises a pair of U- shaped members which are connectedby rivets 3 the inner flanges being spaced apart to receive between themthe end margin of the sheet B. The central frame members 4: comprise apair of U-shaped strips which have their flanges turned toward eachother and separated by spaces to receive the inner end margins of thesheets B, B. The strips 4 are united by rivets 4, the construction beingthe same as illustrated in Fig. 6, so far as the feature of riveting themembers together is concerned.

The upper frame members 2 are shaped similarly to the lower framemembers 1, and ai-e'connectedby rivets 2 in the same manner asillustrated in Fig.1 6. The frame m-em bers 2 are provided at theirouter sides with the curved flanges 2 In the illustration given, a flapof flexible material 5, such as artificial leather, hasone marginsecured between the members 2, while the other 11 argin is secured tothe front how 6 of an automobile top 7.

In the illustration given, the visor is bowed longitudinally, forming apair of reverse curves 8 and 9. That is, in theillustration given, thevisor has two longitudinal curvatures formed about line-centers whichlie on opposite sides of the visor. Accordingly, the transverse framememtoers are given the reverse curvatures shown in Fig. 2, and thecelluloid sheets are provided with corresponding longitudinalcurvatures. In

addition to this, each sheet is provided with transverse ribs 10, formedby pressing'the sheet material upwardly at suitable intervals.Preferably, the ribs are an equal distance from each other and spacedapart about two or three inches. Preferably the ribs terminate a shortdistance from the longitudinal edges of the sheet, thus leavingsubstantially flat margins 11 which are adapted to extend betweenthepairs of frame members. The sheets are slitted at their longitudinaledges and alternate portions are bent at an angle to the sheet to formsmall flanges 12, the intervening portions l2 being left straight,orunbent, so that their edges will forin stops adapted to co-act withthe embossments l which receive the rivets. Thus, the flanges or fiatangular lugs 12 and the projecting plane portions 12 will serveeffectually to prevent the sheet from being withdrawn from the frame,while the embossments l Wlll serve as stops to limit the inward movementof the sheet with respect to the frame member. In practice, the lugs orflanges 12 are not bent sharply at a right angle, andthere would be someliability that the sheet might be pulled out of the frame member were itnot for the plane projections 12 which aid in preventing withdrawal incase the sheet is bent upwardly when a withdrawing force is exerted.

T he end edges of the sheets are notched as indicated at 13 toaccommodate the rivets 3 The visor may be supported on an automobile inany desired manner. In the illustrationgiven, 14 designates in afragmentary way one form of visor-supporting means. The presentinvention is not concerned, however, with the method of supporting thevisor.

From the description given, will be seen that in the preferredconstruction the celluloid sheets are floating sheets, or shiftablewithin certain limits, also that the celluloid sheets are bowedlongitudinally and ribbed transversely. The'longitudinal bowing of thesheets is not ordinarily sufficient to prevent the sheets from sagging.This is true especially wherethe longitudinal curvatures are not madeabout short radii, and it is objectionable, in a visor, to employ shortradii of curvatures for the sheets. The

transverse ribs are preferably formed by beads in the manner illustratedin Fig. 5. These beads not only supply the supplemental strengthening orreenforcing means necessary to prevent buckling of the sheets, but theyalso tend to break up rays of light com ing from a luminous source, thusimproving the visor in this respect. In addition, the hollow transverseribs provide for a certain amount of contraction or expansion of thecelluloid sheets, without causing objectionable general deformation ofthe sheets. These ribs also greatly enhance the appearance of the visor.

The celluloid sheets may be pressed in the orm described in suitablemolds. molds may be heated, or the sheets may be preparatorily heated,if desired. While it is preferred to how the sheets longitudinally inthe manner described, they may be bowed longitudinally in any desiredshape, or this feature may be omitted.

The foregoing detailed description has been given for clearness ofunderstanding only and no unnecessary limitations should be understoodtherefrom, but the appended claims should be construed as broadly aspermissible in view of the prior art. The word celluloid is used in theclaims to designate material having the characteristics of celluloid,whether known by that trade name or by some other name.

lVhat I regard as new and desire to secure by etters Patent, is:

1. In a visor, the combination of a celluloid sheetprovided at itsmargins with flanges, and spaced frame members forming a rectangularframe and receiving between them the marginal portions of the sheet,said frame members being provided with flanges adapted to preventwithdrawal of the margins of the sheet. v

2. In avisor, the combination of a celluloid sheet having marginalflanges disposed at an angle to the main margin of the sheet, and aframe comprising marginal member. provided with spaced flanges whichrecei're freely between them the margins of the sheet.

3. A visor comprising a celluloid sheet provided" at its margins withalternate stop flanges and projecting plane portions and a framecomprising pairs of marginal frame members provided with inturned spacedflanges which receive the margins of the sheet between them, and rivetsconnecting said frame members.
